HINGE FOR SCREENS.

Specication of Letters Patent.

Application led December 15, 1911. Serial No. 665,974.

T o all whom it may concern.'

,Be it known that I, HENRY DrrrMEn, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Hinges for Screens, of which the following is a specification.A

My invention relates to new and useful improvements in hinges for screens, storm windows and the like, and more especially to hinges by means of which the screen may be swingingly mounted to the top of the window frame in such a manner that its lower end may be swung outwardly and the object of my invention is to improve the construct-ion and increase `t-he etlieiency of hinges of the above described type.

A further object of my invention 1s to provide a hinge by means of which the screen may be hung from the inslde of the window thus avoiding the danger commonly encountered in the hanging of screens.

With ythese and other objects in view, my invention will be more fully described, illustrated in the accompanying drawings which show a preferred embodiment of my device, and then specifically pointed out in the Vclaims which are attached to and form a part of this invention. I In t-he drawings, Figure 1 is a fragmentary perspective of a window frame and screen showing my hinge in' use. Fig. 2 is a section on the' line 2-2 of Fig. 1, the position of the parts when the screen is swung outwardly being shown in dotted lines. Fig. 3 is a perspective of the frame member of the hinge. Fig. 4 is a-perspective of the screen member of the hinge. modified form of screen member employed vwhen the hinge is used as a side hinge.

Referring more specifically to the drawings, in which similar reference numerals designate corresponding parts throughout, 10 designates the window casing, 11 the top bar of the screen frame and 12 the customary stop member of the window casing.

As shown my improved hinge consists of two parts 13 and 14 the former of which is secured to the bottom edge of the top member of the window casing and the latter of which is secured to the upper edge of the upper member of the screen frame, said screen frame being recessed to form a space for the hinge members.

The member 13 as best shown in Fig. 3

Fig. 5 is athen upwardly to form a U-shaped bearing member. The hinge member 14 as best Vshown in Fig. 4 of the drawing consists of an L-shaped metal plate forming the body of the member and adapted to be secured to the screen frame. The horizontal portion of this L-shaped member extends beyond the forward face of the screen and is provided with a slot 16 adapted to receive the tongue 15 of the member 13, and said extended por- -tion immediately beyond the slot is bent downwardly and outwardly and then upwardly to form a U-shaped bearing member 17 adapted in operative position to rest within and bear against the U-shaped tongue 15.

In applying my improved hinge the hinge member 13 is secured to the window easing as shown, the screen frame is recessed as at 18, the hinge member 14 is hooked over the tongue 15, the screen is positioned in place and the member 1-4 is secured thereto. A s will be readily seen none of these operations require any of the work being done outside of the building. With the hinge thus assembled the screen can be released only by swinging the same outwardly and upwardly through an angle of nearly 180 degrees and it will therefore be seen that any accidental disconnection of the hinge due to the swinging of the screen is impossible. At the same time the curvature of the tongue 15 and of the portion 17 of the member 14 is such that they bear closely against each other in all positions of the screen and form a satisfactory bearing.

It will of course be understood that I do not wish in any way to limit myself to the employment, of t-he hinge upon the upper end of the screen as the same may be used as a side hinge if desired, or in fact may be. employed for any purpose in which a hinge of this type is fitted for use` without in the slightest degree departing from the spirit of my invention.

When employing the hinge as a side hinge, the screen member is preferably formed as shown in Fig. 5, the tongue 15 being formed Patented J uly 2,1912.

Vabove the center of the plate 13 .andbeing eut away as at 19 to form a lug 20 adapted to engage against the member 14.

lVhat I claim is 1. A separable hinge for screens, comprising two 4plates adapted to be respectively attached to a window easing and to the screen, the former of said plates being provided with a downwardly and outwardly and up'- wardly curved tongue forming a bearing member; and the latter .of said plates being provided with a slot through which said longue is passed whereby the plates are connected, said latter plate being further provided with a downwardly and outwardly and upwardly Curved member adapted to be seated wit-hin and bear against the tongue of the former member when the parts are in operative position.

2. A separable hinge for screens, comprising two plates adapted to be respectively atwith a downwardly, outwardly and upf wardly curved tongue forming a bearing member, said tongue being provided at its free end with a4 laterally directed eXtension, and the latter of said plates being provided with a slot through which said tongue together with its extension is passed whereby the plates are connected, said latter plate being further provided with a downwardly` outwardly and upwardly curved member adapted to be seated within and bear against the tongue of the former member when the partsare in operative position.

In testimony whereof, I atlix my .signature, in presence of two witnesses.

HENRY DITTMER.
